Now--Greek, "But"; it is no wonder there should be now such opponents to the truth, for their prototypes existed in ancient times [ALFORD]. Jannes . . . Jambres--traditional names of the Egyptian magicians who resisted Moses (Exo 7:11, Exo 7:22), derived from "the unwritten teaching of the Jews" [THEODORET]. In a point so immaterial as the names, where Scripture had not recorded them, Paul takes the names which general opinion had assigned the magicians. EUSEBIUS [Preparation of the Gospel], quotes from NUMENIUS, "Jannes and Jambres were sacred scribes (a lower order of priests in Egypt) skilled in magic." HILLER interprets "Jannes" from the Abyssinian language a trickster, and "Jambres" a juggler" (Act 13:8). resist--"withstand," as before. They did so by trying to rival Moses' miracles. So the false teachers shall exhibit lying wonders in the last days (Mat 24:24; Th2 2:9; Rev 13:14-15). reprobate--incapable of testing the truth (Rom 1:28) [BENGEL]. ALFORD takes passively, "not abiding the test"; rejected on being tested (Jer 6:30).
